Saints’ defensive coordinator Spagnuolo relieved of duties

The Saints announced Thursday that first-year defensive coordinator Steve Spagnuolo and secondary cach Ken Flajole have been relieved of their duties with the team.

“I personally want to thank Steve and Ken for their contributions during what was an unprecedented 2012 season,” Saints coach Sean Payton said in a statement released by the team. “Philosophically, we are changing our defense to a 3-4 alignment and right now is the best time to accomplish this transition.”
